Re: RDFCore WG: Datatyping documents

While all of these points are valid, important, and eventually
need to be worked out (mostly, I think, on the RDF side, though
the XML NS spec also needs a little work too), there is currently
a convergence proposal under very serious discussion which will,
for the time being, move the qname and namespace issue outside
of the datatyping solution, as only complete URIs would be used,
and the URIs used would be those that XML Schema (or other
datatype owners) say must be used.

I believe this addresses the primary concerns that have been
expressed regarding the relationship between RDF datatyping
and XML Schema datatypes.

if you haven't already.

Your comments are very welcome.

Cheers,
